OSM is the smallest industry module standard. Currently, there are three main module form factors, SMARC, Qseven, and COM Express. The size based on OSM-L is 45mm x 45mm, which is only 49% of SMARC, 41% of Qseven and 22% of COM Express. This makes the biggest challenge in developing OSM modules to integrate the full functionality of CISC related chips into an OSM form factor, since CISC chips are typically larger than RISC.
